In the drawings -Figu Fig. 2 is n vertical-"central section t ereowing one engine s cylnderpartly in sec#v It is the primary objectofl the invention.'

to obtain a simple. construction-of starting' mechanism which is always-incondition for operation in whatever positionthe encgine may be stopped.` This is' accomplishe by the novel constructionand arrangement of a rotary valve for each` cvlinder of the-en` gine, the ports vof which, in addition to the perfomancepofitheir usual functions, are] arranged to coperate with an inletl p ort for com ressed air which is used in' starting valve:4 forv ,fthe conduit '.-leadngiajfroinfthev 1: H ail-whichvwll the airv to pass*y to thef various cylinders`,. one I of 'the valveabeing inr position. toi admitthe 1 air, and to operatethe pistons thereby In detail, A is the' casing of a multi-cyliii'-y der engine, -and` I the head ofeach cylinder. and

With a four cycle engine oth of these ports will be closed during the ower strokes of the engine, the -port C in the valve being out of registration therewith' and traveling around beneath an imperforate portion o the. cylinderhead.y

Theinlet p'ort for the com ressedair used instorting, is arranged in hat portion of the head usually imperforate and is so positioned that the air will be admitted during Specification ofLetterl Patent. Application tiled February 4, 1911. Serial No. 606,532.

Thus, as shown, F is the a mission port in the head of the cylinder which is connected with an 4 positioned to register with the ports C when out of registration with the ports D and E. The mouth .or opening of thisport F is preferably elongated so that some portion of the port in one ofthe. cylinders will be in registration with the port `C of .the corresponding valve,

the result being that .theen 'ne will start whenever the controlling va ve, such as H forthe conduit vG is open.
